Question

if one card is selected at random from a deck of 52 playing cards, what is the probability that the card is less than 5 , a 4 or both?​

Answer 1

Total no. of possible outcome= 52

P(a card less than 5) = (4x4)/52 = 16/52 = 4/13

P(a 4)= 4/52=1/13

P(both)= 4/52 = 1/13

P(a card less than 5 , a 4 or both)= 16/52 = 4/13
